Feathered Friends
Birds are warm-blooded vertebrates (animals with backbones). They are unique
animals, because their bodies are covered with feathers. Instead of front legs or
arms, birds have wings and most can fly.

Amazing Amphibians
Amphibians are cold-blooded vertebrates (animals with backbones). They have
no scales on their skin. Most amphibians hatch from eggs laid in water or on
damp ground. Many amphibians grow legs as they develop into adults. Some
live on land and have both lungs and gills for breathing. Frogs and toads are
examples of amphibians.

ORGANIZATION OF LIVING THINGS
Classroom Assessment Example SCI.III.2.E.1
(Explain characteristics and functions of observable body parts in a variety of animals.)
Each student will invent an animal that shows an observable body part for each of the following
functions: insulation, support, movement, food gathering, and protection. Each student must
present his or her design in one of the following forms: storybook, flipbook, multi-media
presentation, 3D model, or drama.
This presentation must also include a written explanation of the body’s observable
characteristics and the function that each fulfills. Written presentations may be in one of the
following forms: story, poem, song, or report.

ORGANIZATION OF LIVING THINGS
Classroom Assessment Example SCI.III.2.E.2
(Compare and contrast familiar organisms on the basis of observable physical characteristics)
Post the six animal characteristics (backbone, skin, shell, limbs, feathers, and scales) (See Key
Concepts). Have students brainstorm a list of animals for each of the six categories. Students should
then choose two of the categories. Challenge each student to consider the similarities and differences
among the animals in the categories he or she has chosen and to create one more division for each
category based on personal observation. Each student will then design a graphic organizer (see
graphic organizer in resources) that begins with animals (Level I) and is divided into two of the
posted categories (Level II). From there, the student will divide each of the two chosen categories
once more based on personal observation (Level III). The graphic organizer is then completed by
adding the names of the animals from the original brainstormed list (Level IV).
(Give students rubric before activity.)
